Welcome to the Friends of Stocker's Lake Website

This website is owned and maintained by Friends of Stocker’s Lake (FoSL), a registered charity. FoSL exists to :

  1. - conserve, safeguard and enhance Stocker's Lake as a Local Nature Reserve
  2. - help and extend the scope of the work of the warden at Stocker's Lake
  3. - foster public support for and appreciation of Stocker's Lake as a local nature reserve.

Stocker's Lake, near Rickmansworth just inside the M25, is bordered on one side by the river Colne and on the other by the Grand Union canal. It is a place of great beauty and it supports a huge variety of wildlife, especially birds, particularly winter wildfowl. It is owned by Affinity Water and managed by Herts & Middlesex Wildlife Trust, actively supported by local people who are the Friends of Stocker’s Lake.

Within this website you will find details of organised walks and other events on the reserve, news of interesting recent sightings of birds, details of how to join FoSL for a mere £5 per year, and much more.

We are now monitoring water voles on the reserve. Water voles were once common mammals in British waterways but their numbers have declined by over 90% due to habitat loss and predation by the non-native American mink.

More butterflies were counted at Stocker's Lake in 2017 than in any other year since we recommenced regular systematic monitoring in 2012. Using the same methodology as in previous years, a total of 817 butterflies were counted in 2017. This is 72% up on 2016.

Herts and Middlesex trust are building a kingfisher nest site on the reserve. Rumour has it that this will feature on BBC's Countryfile programme on Sunday November 19th (BBC1, 6.15pm), when the programme is scheduled to visit Hertfordshire.

Emma Brading has taken over as our volunteers organiser from Sarah Coombs, who has been doing the job for the past 15 years or so.  Sarah is one of the original FoSL members and has done much for the reserve particularly in the early years of FoSL.  We are very grateful for what she has done and thank her most sincerely.  We're glad to say that she continues as a member.
